Parker S604-70 O-Rings Offer Innovative Solutions for Performance Consistency


Material compounding and processing often cause performance inconsistencies that affect Silicone Rubber (Q, MQ, VMQ, PVMQ) O-rings, even when used in equal applications. At Zatkoff Seals & Packings, we eliminate these performance irregularities with S604-70 O-rings from Parker Hannifin, an industry leader in elastomeric technology.

Our commitment to consistently deliver innovative products is evidenced by our comprehensive inventory of Parker O-Rings. We currently offer nearly a half million in-stock Parker S604-70 O-rings, thus ensuring your access to innovative solutions for a variety of VMQ O-ring applications.

Known for providing excellent resistance to ozone, aging, and weather, S604-70 also possesses good insulating and physiologically neutral properties. Additionally, S604-70 offers exceptional chemical resistance to high molecular weight chlorinated aromatic hydrocarbons, including flame-resistant insulators and coolant for transformers. However, due to its silicone elastomer polymer, S604-70 typically demonstrates relatively low tensile strength, poor tear strength, and little wear resistance.
